BOUT-FACING: OAR.

Application filed November 19, 1919.

To all whom it may concern.-

lie it known that I, FERDINAND KoHL, a citizen of the United States, residing at Plymouth, in the county of Sheboygan and State of Wisconsin, have invented a new and useful Bow-Facing Oar, of which the following is a specification.

My invention relates to new and useful improvements in rowing cars, and more particularly to that type of oar which makes it possible for the oarsman to face the bow of the boat, or in the direction in which the boat is moving when the oars are actuated.

An important object of the invention is to provide a device of the above named nature which is highly eliicient in practice, and which includes parts which are manufacturable at a minimum cost, strong, durable, and may be readily assembled for replacement or repaired.

Another object of the invention is to provide means for mounting the Various parts of the invention which can be readily associated withboats of the well known type.

lVith the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings, forming a part of the description and wherein like numerals are employed to designate like parts throughout the several views.

Figure 1 is a transverse section through a boat showing my invention applied to one side thereof;

Fig. 2 is an enlarged fragmentary view of the device unapplied;

Fig. 3 is a top plan of the invention with handle member removed; and

Fig. 4 is a front elevation of the stand ards journaled in suitable bearings.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 designates a conventional type of row boat, the sides of the boat being equipped with one of my improved cars. A standard 6 is equipped with a T-shaped member 7, the oppositely extending branches 8 of which Specification of Letters Patent.

Serial No. 339,085.

connected hollow portion 10 a substantial distance above the bearings 9.

The blade member 11 assumes the form of a disk as does the handle member 12. The upper face of the blade member and lower ace of the handle member are each equipped with circumferentially arranged gears or gear teeth 13 adjacent the edges of the disk, and each disk is provided with a central opening 14. A bolt 15 is provided or formed upon the upper face of the blade member 11 and the lower face of the handle member 12 to surround the openings let eX- tending therethrough.

In most cases the blade member and the handle member are rotatably mounted upon the standard 6, the handle member being arranged above the blade member with its gear 18 facing the gear of the blade memer. a support for the blade member, whereby this member is supported in spaced relation to the bearings 9. Secured to the standard, and interposed between the members 11 and 12, is a spider 16, which in the present i11- stance, is equipped with four radiating spider legs 1?. A beveled gear 18 is rotatably mounted upon the outer end of each leg 17 to mesh with the gears 13 of the members 11 and 12. In order that the blade and handle member may be retained upon the standard with their gears 13 in mesh with the beveled gears 18, the upper end of the standard is screw threaded to receive a nut 19 which abuts with the upper face of the handle member 12.

Each of these members 11 and 12 is provided with a laterally extending tubular pocket 20, the pocket of the member 12 being adapted to receive the handle portion of the cars, while the pocket of the member 11 is adapted to receive and retain the blade portion of the oar.

In view of the foregoing, it will be manifest that the oarsman may be seated in the boat equipped with my inventiomfacing the bow of the boat or in the direction in which he is traveling, and by pulling upon the handle portion of the oars the blade portions thereof, will be caused to move in the The collar 10 of the'standard forms same direction as the handle portion. After a stroke has been made, the oar together with the standard is tilted in the bearings 9 so that the blade portion is raised out o1 the water. The oarsman then pushes upon the oars in the usual manner to place the oars in a position for the next stroke. The

removedand stored away for future use.

The standards may be retained attached to the heat, so that when it is desired to row again, the members 11 and 12 together with the spider are slipped upon the standards after the nut 19 is threaded thereon to retain said parts intheir proper relation.

Having thus fully described the invention what is claimed is:

1. A bow facing oar including a standard, handle member mounted thereon, a blade member mounted on the standard, each member being equipped with a gear upon adjacent faces, a spider secured to the standard between said members and a beveled gear mounted on each spider leg to mesh with the gears on the twormembers tor causing the two members to turn in the same direction.

2. A bow facing oar including a pair of brackets, a standard having a T-shaped head supported in the brackets, said standard adapted to pivot with relation to the brackets, blade members adapted to rotate on the standard, each of saidblade members having beveled gears formed thereon, a spider secured to the standard, said spider having a plurality of beveled pinions supported thereby, said spider being positioned between the beveled gears of theblade members, whereby movement of one of the blade members producesa relative movement of the opposite blade member. i

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
